Actually, The reason the county created the law was to keep
immigrants from living with 28 people in one house NOT intended as a multifamily residence.
Some neighbor in this high end neighborhood is being an A hole and reporting it.
Your reason is what I came up with also. I’ve seen illegals occupying a house in a subdivision. More cars than you could count, as many different people. Even RVs parked on the curb with extension cords to the house and the toilets hosed to the storm sewers. They destroy the value of a neighborhood quicker than anything else would.
Then haul the Illegal Invaders off to jail, arrresting them as soon as they are released again, and leave Property Owners elsewhere alone. If that was the reason for that law then it was a very C.S. way of dealing with illegals and accomplishes nothing more than to harass legal legitimate property owners who pay property taxes.
I would also bet no city official has had the guts to approach the homes in a situation you mention because Illegals have become a protected class. Many families with man and wife working and kids at driving age have three and four cars.
This type of enforcement makes as much sense as the sanctuary city in my county that because of people {mainly illegals} running red lights put up traffic light cameras. Guess who got fined. Guess who didn't? Guess who had licensed plates registered to an actual correct residence and actual correct legal name of owner of the vehicle. Guess who didn't. The smaller towns in the county aren't as accommodating to the illegals nor is the county LEO but that city is full of government employee liberals. The allowed and ignored offenses of the illegals became so bad I stopped going to that city and shop elsewhere. Enough legal citizens protested them being the only ones paying fines and the cameras got taken down at the end of the contract. But the city depends heavily on it's largest employer the D.O.E. and D.O.D. for jobs so it dares not harass illegals.
